This commit is a preparation for the configuration file parser.
The `int attr_*` variables have been moved into a separate struct.
Members of that struct are alphabetically ordered, so an attribute can
later be accessed by its name.
Added `int get_color_pair(short fg, short bg)` for returning or
creating a color pair number.
Added call to `use_default_colors()` for enabling access to the
terminal's default color (-1).

This commit is a preparation for making keybindings configurable.
The hardcoded keys in the switch statements of mixer_widget.c,
textbox.c, proc_files.c and card_select.c have been replaced by
command enums. The command that shall be executed is looked up in
the arrays `mixer_bindings` and `textbox_bindings`.
The channel_mask enum has been made public, since LEFT and RIGHT are
used as command arguments in bindings.c.

When a multi-column character would straddle the left window border of
a text box, we have to take the inserted space character into account
when we compute how many characters fit into the rest of the line.
